Direct from the Manufacturer: Aluminum-lined Warm Pet Kotatsu (plain), Large Rectangular 100 X 170 Cm, Ivory.

This is a "Kotatsu Pet (Kotatsu Mat) with an aluminum sheet" designed to enhance heat retention. The outer fabric is made of warm blanket material. The aluminum sheet blocks cold air from the floor, and the reflected heat from the sheet further retains the warmth of the kotatsu (heating appliance). It also prevents the kotatsu legs from directly touching the floor, protecting it from scratches. It's ideal for rooms where large mats or carpets cannot be used.

The aluminum sheet is soft and breathable, preventing moisture buildup, and is finished with a process that eliminates rustling noises.

Besides being a kotatsu mat, it can also be used as a single-person rug. It's machine washable at home (use a laundry net). Avoid tumble drying.
